An elongated double-acting hydraulic cylinder 232 has its base end 234 pivotally secured to bracket 236, which is secured to the back wall 160, by pin 238. The rod end 240 of hydraulic cylinder 232 is pivotally connected to bracket 242, which is secured to end 216 of door 210, by a pivot pin 244. A collar 246 is secured to end 174 of back wall 160 as seen in FIG. 5. A pair of spaced-apart

collars

248 and 250 are secured to end 216 of door 210 as also seen in FIG. 5. When door 210 is closed, the

collars

248 and 250 receive collar 246 therebetween. A lock pin 252 is removably extended downwardly through

collars

248, 246 and 250 to maintain or lock door 210 in its closed position.

The numeral 254 refers to a double-acting hydraulic cylinder which has its base end 256 pivotally secured to bracket 258, which is secured to back wall 160, by a pin 260. The rod end 262 of cylinder 254 is pivotally secured by pin 263 to locking bar 264 which is pivotally secured to end 174 of back wall 160 by a pin 266. Locking bar 264 includes an elongated bar portion 268 and an offset bar portion 270. When door 210 is closed, the hydraulic cylinder 254 is extended which causes the locking bar 264 to pivot to the position of FIG. 5 whereby the offset bar portion 270 is positioned outwardly of shaft 220 of door 210 to positively maintain or lock door 210 in its closed position. FIG. 6 illustrates the hydraulic cylinder 232 in its extended position which is made possible by retracting hydraulic cylinder 254 thereby pivoting locking bar 264 away from pin 220.

The above explanation describes the pivoting and locking devices which are located at the rearward end of the door 210 and the rearward left side of the hopper 134. Identical pivoting and locking devices are provided at the forward end of door 210 and the forward left side of the hopper 134. The pivoting and locking devices at the forward end of the door 210 will be designated with a “′”.

The numeral 272 refers to a tandem landing gear assembly of conventional design which is secured to the trailer by braces 274. The landing gear assembly 272 adjustably supports the forward end of the trailer 10 when the trailer is disconnected from the towing vehicle.

The numeral 276 refers to a secure box which is mounted on the front side of front wall 178. The hydraulic power unit for the

hydraulic cylinders

232, 254, 232′ and 254′ and valving therefore is located in box 276 with the same being connected to the tow vehicle battery in conventional fashion.

The functioning of the trailer 10 will now be described. The door 210 will be initially closed by retracting the

hydraulic cylinders

232 and 232′. During the closing of door 210, the

hydraulic cylinders

254 and 254′ will be in their retracted positions. When the door 210 is closed, the locking of the same will be performed. The locking pin 252 will be extended downwardly through the

collars

248, 246 and 250. The hydraulic cylinder 254 is then extended so that the locking bar 264 will be pivoted to the position of FIG. 5 so that the lower offset portion 270 thereof will be positioned outwardly of pin 220. The same procedure will be performed at the forward end of door 210. The locking pin 252′ will be extended downwardly through the collars 248′, 246′, and 250′. The hydraulic cylinder 254′ is then extended so that the locking bar 264′ will be pivoted to the position of FIG. 9 so that the lower offset portion 270′ of locking bar 264′ is positioned outwardly of the pin 266. Thus, the door 210 is positively and safely locked in its closed position to prevent the contents of the hopper 134 from being inadvertently discharged from the hopper.

The hopper 134 will then be filled with material. The

loading ramp members

68 and 70 will then be pivotally moved to their extended position. A skid-steer vehicle or other vehicle may be driven upwardly and forwardly over

ramp members

68 and 70, up the tail portion 67 and onto the deck 72 of trailer 10. The

loading ramp members

68 and 70 will then be pivotally moved to their stowed positions.

The trailer 10 will then be towed to its desired location. The

hydraulic cylinders

254 and 254′ will then be extended to move the offset portion 270 away from pin 220 and to move the offset portion 270′ away from pin 266. The

hydraulic cylinders

232 and 232′ will then be extended to open door 210 to permit the material within hopper 134 to be discharged from the left side thereof and the left side of the trailer.

Thus it can be seen that the invention accomplishes at least all of its stated objectives.

Although the invention has been described in language that is specific to certain structures and methodological steps, it is to be understood that the invention defined in the appended claims is not necessarily limited to the specific structures and/or steps described. Rather, the specific aspects and steps are described as forms of implementing the claimed invention. Since many embodiments of the invention can be practiced without departing from the spirit and scope of the invention, the invention resides in the claims hereinafter appended.
